n: a substance that is an insulator, or nonconductor, of electricity.

a material that does not conduct electricity or has only a low electrical conductivity compared to a metal.

n: 1. a chemical that, when dissolved in water, dissociates into positive and negative ions, thus increasing its electrical conductivity. See dissociation. 2.the electrically conductive solution that must be present for a corrosion cell to exist.

n: A substance that dissociates into charged positive and negative ions when in solution or a fused state. This electrolyte will then conduct an electric current. Acids, bases, and salts are common electrolytes.


a material that, when dissolved in water, causes or increases the fluids’ electrical conductivity.

n: a method that testes drilling pipe. Using interchange coil to magnetize drilling pipe, then couple transformer with primary coil, people record the data of electrical conductivity, magnetic inductive capacity and rigidity.

n: a meter used to measure the electrical conductivity of liquids.

n: opaque crystalline material, usually of high strength, that has good thermal and electrical conductivity, ductility, and reflectivity.

n: a solid (such as gennanium or silicon) whose electrical conductivity lies between that of a conductor and that of an insulator. Semiconductor materials are used in the manufacture of diode rectifiers, transistors, and integrated circuits.
